(A) Any permitted land disturbance operation shall meet or exceed the design criteria set forth in Madisonville’s most recent Standards and Guidance for Development Manual and the Madisonville Best Management Practices Manual, the provisions of which are incorporated herein by reference.
(B) Clearing and grading of natural resources, such as forests and wetlands, and other natural features of concern shall not be permitted, except when in compliance with all sections of this chapter as well as any regional, state and federal regulation. Clearing techniques that retain natural vegetation, drainage patterns, and buffers along streams as described by the manual, shall be used to the satisfaction of the city.
(C) Clearing, except that necessary to establish sediment control devices, shall not begin until all sediment control devices have been installed and have been stabilized.
(D) Inspection/maintenance of erosion control shall be done every seven (7) days and after storm events of one-half (1/2) inch of precipitation or more.
(E) Phasing shall be required on all sites disturbing greater than thirty (30) acres, with the size of each phase to be established at plan review and as approved by the city.
(F) Erosion protection BMP requirements:
(1) Soil stabilization shall be completed within fourteen (14) days of final grade work. If an area is left inactive for twenty-one (21) days or more, the area shall have temporary stabilization.
(2) If seeding or other vegetative erosion prevention methods are used, vegetation shall become established within three (3) weeks. If a satisfactory stand of vegetation is not established, the city may require the site to be reseeded or a non-vegetative option employed.
(3) Special techniques such as rip rap, turf reinforcement, armoring, and other methods that meet the design criteria outlined in the manual on steep slopes or in drainage ways shall be used to ensure stabilization.
(4) Soil stockpiles must be stabilized or covered and have sediment control measures in place to control sediment movement. Stockpiles shall have temporary vegetation established if it is going to be left for twenty-one (21) days or more.
(5) When construction is suspended for twenty-one (21) days or more, the entire site must be stabilized using a heavy mulch layer or other methods that do not require germination to control sediment and prevent erosion at the close of the construction season.
(6) Minimize clearing and grading to the smallest possible area. Preserve existing vegetation and trees to the maximum extent possible.
(7) Areas to be left undisturbed during construction shall be clearly noted and delineated on the plans.
(8) Vegetative buffer strips in combination with other perimeter controls shall be used for the protection of adjacent properties, watercourses, and right-of-ways
(9) Measures to control sedimentation deposits into drainage structures and features, receiving water bodies, natural karsts features, roads, right-of-ways, and adjacent properties.
(G) Sediment control BMP requirements shall include the following:
(1) Dust control techniques shall be employed to prevent the blowing of dust by air movements during land disturbance, demolition, and other construction activities.
(2) Diversion of upland runoff past disturbed slopes shall be implemented when necessary.
(3) Settling basins, sediment traps, tanks and/or perimeter controls shall be implemented as required by the city’s manual to control sediment.
(4) Effective debris and trash management shall be required.
(H) Waterway, watercourse, short-lived stream, and public storm drain protection requirements shall include the following:
(1) A temporary stream crossing installed and approved by the Kentucky Division of Water and the city, if a watercourse will be crossed regularly during construction.
(2) Stabilization of the watercourse channel before, during, and after any in-channel work.
(3) Design of all on-site storm water conveyance channels in accordance with criteria outlined in the city’s manual.
(4) Stabilization adequate to prevent erosion located at the inlets and outlets of all pipes and paved channels.
(I) Construction site access requirements designed to minimize the deposit of sediment or other materials on public streets and rights of way shall include the following:
(1) Continuous access via a stabilized rock entrance, constructed in accordance with the city’s manual.
(2) At the city’s discretion, exercised in good faith, a tire wash rack may be required.
